docs: add 7 workflow docs and update skill/readme cross-references

New workflow docs:
- workflow-token-research.md — pre-buy token due diligence
- workflow-wallet-analysis.md — wallet quality assessment
- workflow-smart-money-profile.md — trading style analysis and copy-trade ROI estimate
- workflow-risk-warning.md — active risk monitoring (whale exit, liquidity, dev dump)
- workflow-early-project-screening.md — new launchpad token screening
- workflow-daily-brief.md — daily market overview
- workflow-project-deep-report.md — comprehensive token analysis with scored dimensions

Renamed docs for consistent workflow- prefix naming:
- market-discover-opportunities.md → workflow-market-opportunities.md
- token-due-diligence.md → workflow-token-due-diligence.md

Updated SKILL.md files (portfolio, track, token, market, swap) with workflow
cross-reference links at relevant trigger points. Updated CLAUDE.md quick
decision table and workflow docs index. Added Workflow Docs section to
Readme.md and Readme.zh.md.

+# Full Token Due Diligence — 4-Step Workflow
+
+Use this workflow before deciding to buy a token. Run all four steps in sequence.
+
+## Step 1 — Get basic info
+
+```bash
+gmgn-cli token info --chain sol --address <token_address> --raw
+```
+
+Check: `price`, `liquidity`, `holder_count`, `wallet_tags_stat.smart_wallets`, `wallet_tags_stat.renowned_wallets`, `link.website` / `link.twitter_username` / `link.telegram`.
+
+**Red flags**: all `link.*` social fields empty, very low liquidity (<$10k), zero `wallet_tags_stat.smart_wallets` and `renowned_wallets`.
+
+## Step 2 — Check security
+
+```bash
+gmgn-cli token security --chain sol --address <token_address> --raw
+```
+
+Check these fields and their safe thresholds:
+
+| Field | Safe | Warning | Danger |
+|-------|------|---------|--------|
+| `is_honeypot` | `"no"` | — | `"yes"` → Do not buy |
+| `open_source` | `"yes"` | `"unknown"` | `"no"` |
+| `owner_renounced` | `"yes"` | `"unknown"` | `"no"` |
+| `renounced_mint` (SOL) | `true` | — | `false` → mint risk |
+| `renounced_freeze_account` (SOL) | `true` | — | `false` → freeze risk |
+| `buy_tax` / `sell_tax` | `0` | `0.01–0.05` | `>0.10` → high tax |
+| `top_10_holder_rate` | `<0.20` | `0.20–0.40` | `>0.50` → whale risk |
+| `rug_ratio` | `<0.10` | `0.10–0.30` | `>0.30` → high rug risk |
+| `creator_token_status` | `creator_close` | — | `creator_hold` → dev not sold |
+| `sniper_count` | `<5` | `5–20` | `>20` → heavily sniped |
+
+## Step 3 — Check liquidity pool
+
+```bash
+gmgn-cli token pool --chain sol --address <token_address> --raw
+```
+
+Check: liquidity amount, which DEX (`exchange`), pool age (`creation_timestamp`). Low liquidity means high slippage risk when buying or selling.
+
+## Step 4 — Check smart money signals
+
+```bash
+# Is smart money accumulating?
+gmgn-cli token holders --chain sol --address <token_address> \
+  --tag smart_degen --order-by buy_volume_cur --direction desc --limit 20 --raw
+
+# Have KOLs already taken profit?
+gmgn-cli token traders --chain sol --address <token_address> \
+  --tag renowned --order-by profit --direction desc --limit 20 --raw
+```
+
+**Bullish signals**: smart_degen wallets buying heavily, unrealized_profit is large (still holding), renowned wallets accumulating, low sell_volume_cur.
+
+**Bearish signals**: sell_volume_cur > buy_volume_cur for smart money, large realized profits already taken (they may be done), top holders with very high amount_percentage starting to sell.
